Thanks.I wrote some code to count the number of prescriptions and had originally restricted later analyses to RX = 1, but as we can see, that doesn't work for people with multiple scripts on the same encounter (Patient 2222). data pt_meds_; set pt_meds; by patient_num; if first.patient_num then RX = 1; else RX + 1;

Then your next two lines replace you WORK.P2_DATA dataset. Then you PROC SQL code tries to replace the WORK.P2_DATA datsaet with itself again. If you want to print 10 observations just use the OBS= dataset option. proc print data=sasuser.p2 (obs=10); run; View solution in original post. 0 Likes.As Paige said, the best tool is data step,NOT sql. Anyway, there is some sql code could get first last. But I don't like it. proc sort data=sashelp.class out=have;by sex;run; ods select none; ods output sql_results=sql_results; proc sql number; select * from have; quit; ods select all; proc sql; create table want as select * from sql_results group by sex having row=min(row) or row=max(row); quit;SAS date values are counts of days with 1960-01-01 as day zero. For comparisons, formats are irrelevant, so you best store raw, unformatted values in macro variables (see Maxim 28). To get first and last day of the current month, use INTNX:

Solved: Hi, Am just trying to concatenate first and last name in the following format: Doe, Jane Simple concatenate keeps giving me DoeJane. How do I.Hi, Really annoyed with myself that I can't figure this out (or find the answer online). I have a dataset that covers the last four years (a single month end entry for each account) of accounts moving through arrears cycles and I am trying to identify the first and last occurrence of each account being at each level of arrears cycle so I can calculate …

In that case, SAS would not set any flags or automatic variables other than _N_, _ERROR_, etc. However, if you WANT to use FIRST.byvar and LAST.byvar processing then you have to "turn them on" with a BY statement inside your DATA step program. So the 2 BY statements in your code are really independent of each other.Hi there, I am trying to assign First and Last to a row that meets a number of conditions. I have sorted the table by ID# and Location and Key Date. A row must meet all 3 conditions (A,B,C) = 'Yes', otherwise it will skip to the next row (within the group ID# and Location) to assign First or La...Any one have any ready made macro to get different days of the month into Date9. format. first day of the month, first day of the last week Last day of the last week last saturday of last week First day of the current week etc.. some thing similar data _null_; yday=put(date()-1,date9.); today=put(d...Re: first.* is unitialized. In order to use first. syntax, you must use a BY statement in your data step: BY code; The =1 is unnecessary, it is implied TRUE. And I don't believe you can use FIRST. together with WHERE (since WHERE does not aware of what is going on in the data step, IF is). /Linus.Here's an example of how that would work. Some efficiency tricks: Use format dtdate9 on your datetime variable to summarize data by date. Use Range for the date variable to obtain the max time - min time. Datetime is stored as seconds, so convert to a number by dividing by 60 for minutes and another 60 for hours.

E.g., if I was wrong and you only want the first and last records, then the following might suffice: data want; set have end=last; if _n_ eq 1 or last then output; run; Conversely, if you actually do need the minimum and maximum dates in the file, then you could use something like: data want (drop=_:); set have end=last;

Finding duplicates is simple with SAS “FIRST.” and “LAST.” expressions. Find duplicates save resources, ie, money, that can be used for other tasks. Using the FIRST. And LAST. expressions is a quick and easy way to find duplicated data. Using SAS expressions can save a lot of coding time. Author Clarence Wm. Jackson, CSQA

Posted 04-14-2020 10:55 PM (961 views) Hi 🙂. I want to create a conditional variable (outcome) based on accident_id and road_user_type: - if anyone in an accident was a vulnerable road user > then outcome = 1; - else if everyone in an accident was a MVO > then outcome = 2; - else outcome = 3. In SAS you can easily extract characters from a string using SUBSTR() or SUBSTRN() functions.But it only works with the character variable. To extract last 4 digits or any number of digits from a numeric variable, you need to convert the input from numeric variable to character variable in order to use substr function.. You have to do this conversion but it is very straight forward.Finding duplicates is simple with SAS “FIRST.” and “LAST.” expressions.

Comparisons. The PRXCHANGE function is similar to the CALL PRXCHANGE routine except that the function returns the value of the pattern-matching replacement as a return argument instead of as one of its parameters. The Perl regular expression (PRX) functions and CALL routines work together to manipulate strings that match patterns.To accomplish, he sorted the data on multiple columns with case_id as the first criteria. Then he sorted the data again with proc sort nodupkey by case_id to return the top record for each case_id. If his original sorting criteria is correct, he will return the most impacting sub-action for each case_id.Hear from SAS execs, best-selling author Adam Grant, Hot Ones host Sean Evans, top tech journalist Kara Swisher, AI expert Cassie Kozyrkov, and the mind-blowing dance crew iLuminate!

If so, then you only need: data get_first_and_last; set master_table; by ID Date; if first.date or last.Date then output; run; Of course, if you only want the last record on a date then replace the if with:

In particular, the program answers the programmer's question by showing a concise "one-liner" that you can use to get the first and last days of the previous month.Jun 16, 2020 ... ... first, last and between By-group processing ...

In a WHERE expression, you cannot use automatic variables created by the DATA step (for example, FIRST. variable, LAST. variable, _N_, or variables created in assignment statements). As in other SAS expressions, the names of numeric variables can stand alone. SAS treats numeric values of 0 or missing as false; other values as true.

Then, we create a data step with two output data set. One with unique observations and one with the duplicate observations. Finally, we use the first keyword to move the first unique observation of the data set to the output data set …The same record is also the last record of home circle for Alan. So for last. circle = 1, we just add the variable tot_usage to the output dataset tot_usage in Step 3. For Alan, the second record is the first occurrence of circle = roaming, so Step 1 – 2 is repeated. The value of tot_usage now is 540.I have a dataset that has variables ID, Date, and Value.

You must logically find a certain row. So for instance if in a datastep you had first and last of dates within ID, and they were sorted sequentially and they were unique, the "first" row would logically be identified by date=min (date) group by id. The "last ...

4.

If the input data sets have different numbers of observations, the END= variable is set to 1 when MERGE processes the last observation from all data sets. Tip: The END= variable is not added to any SAS data set that is being created. culpepper funeral Example 1: Using the SCAN Function in SAS and CAS. This example uses the SCAN function to scan first and last names and output the names. This code processes the data in SAS. The DATALINES statement is supported in SAS but not in CAS. A negative count instructs the SCAN function to scan from right to left.This is a SUM statement . SAS evaluates boolean expressions to 1 (TRUE) or 0 (FALSE). So when FIRST.Y is TRUE it has a value of 1. So when this observation is the first one with this value of Y (within the current value of X) the counter is incremented by 1.
